or, if you insist on one line:
btw., the effect of "export" on a variable is lasting. You do not need the also oftenly seen:
Once a variable is exported, it stays exported ("exported" means: its current value is copied to the environment of any child process it creates) and if you change its value then this new value instead of the old one would be copied to a newly inherited child.
If you "dot-execute" a script like this:
this means that it is executed in the current envrronment instead of creating a new one at the start which is closed at the end (which is the default). This is why changes to the environment are lasting. On the other hand you can use any shell device there is, including control structures.
